Campanula plant named ‘Bkpcmpjy’

ABSTRACT

A new and distinct cultivar of  Campanula  plant named ‘Bkpcmpjy’ characterized by its upright to outwardly spreading plant habit; freely branching habit; early and freely flowering habit; campanulate-shaped flowers with bright purple violet-colored petals; and good garden performance.

Botanical designation: Campanula portenschlagiana.

Cultivar denomination: ‘BKPCMPJY’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Campanula plant, botanically known as Campanula portenschlagiana, commonly known as Dalmatian Bellflower and hereinafter referred to by the name ‘Bkpcmpjy’.

The new Campanula is a product of a planned breeding program conducted by the Inventor in Maasdijk, The Netherlands. The objective of the breeding program is to create new freely flowering Campanula plants with attractive flowers and good interior and garden performance.

The new Campanula plant originated from a cross-pollination conducted by the Inventor in Maasdijk, The Netherlands in June, 2008 of a proprietary selection of Campanula portenschlagiana identified as code number 4400102, not patented, as the female, or seed, parent with a proprietary selection of Campanula portenschlagiana identified as code number 4400293, not patented, as the male, or pollen, parent. The new Campanula plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled outdoor nursery in Maasdijk, The Netherlands in June, 2009.

Asexual reproduction of the new Campanula plant by cuttings in Maasdijk, The Netherlands, since February, 2010 has shown that the unique features of this new Campanula plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Campanula have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Bkpcmpjy’. These characteristics in combination distinguish ‘Bkpcmpjy’ as a new and distinct Campanula plant:

-   -   1. Upright to outwardly spreading plant habit.     -   2. Freely branching habit.     -   3. Early and freely flowering habit.     -   4. Campanulate-shaped flowers with bright purple violet-colored         petals.     -   5. Good garden performance.

Plants of the new Campanula differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Campanula are broader than plants of the         female parent selection.     -   2. Plants of the new Campanula flower earlier than plants of the         female parent selection.     -   3. Plants of the new Campanula have larger leaves than plants of         the female parent selection.

Plants of the new Campanula differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Campanula have smaller and darker         green-colored leaves than plants of the male parent selection.     -   2. Plants of the new Campanula and the male parent selection         differ in flower color as plants of the male parent selection         have pale blue-colored flowers.

Plants of the new Campanula can be compared to plants of Campanula portenschlagiana ‘PKMp01’, disclosed in U.S. Plant Pat. No. 17,205. Plants of the new Campanula differ primarily from plants of ‘PKMp01’ in the following characteristics:

-   -   1. Plants of the new Campanula are broader than plants of         ‘PKMp01’.     -   2. Plants of the new Campanula have larger leaves than plants of         ‘PKMp01’.     -   3. Plants of the new Campanula flower earlier than plants of         ‘PKMp01’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown in 12-cm containers during the early summer in a glass-covered greenhouse in Maasdijk, The Netherlands and under cultural practices typical of commercial production conditions. During the production of the plants, day temperatures ranged from 15° C. to 19° C. and night temperatures ranged from 14° C. to 16° C. Plants were 13 weeks old when the photographs and description were taken.
